AMS Performance Archetype custom M157 twin turbo V8 dyno tune results on an E63 AMG and CLS63 AMG
The name AMS should be familiar to many of you due to their work on the Nissan GTR and their well known "Alpha" packages for that vehicle. AMS is tackling the new M157 twin turbo 5.5 liter V8 platform for the Mercedes 63 AMG vehicles and below we have two dynojet dyno graphs of their custom tune which they refer to as Archetype. The first graph is the E63 AMG which shows a huge torque increase of over 225 pound-feet at the wheels.
The second graph is a CLS63 AMG which sees similar torque gains and slightly more peak horsepower. The CLS sees over 100 wheel horses and 200 wheel torque gained which is nothing to sneeze at.
The M157 platform is going to be seeing a lot of action in the next few years with all kinds of tuners getting into the mix that previously may not have been associated with the Mercedes tuning scene.
